摘要： A liquid epoxy resin is produced by gradually feeding an aqueous solution of alkali metal hydroxide into a solution of bisphenol-A in epichlorohydrin, while maintaining the reaction medium at boiling point, distilling off water in the form of an azeotrope with epichlorohydrin and recycling the latter, and maintaining a water content of from 0.1 to 0.7 wt.% and a pH value between 7 and 9 in said reaction medium. The liquid epoxy resins thus obtained have low values of the viscosity, epoxy equivalent and hydrolyzable chlorine content.

摘要： Resinous substance suitable for use as film-forming component in anti-corrosive and can-coating paint and varnish compositions, which consists of the product obtained by reacting a normally solid polyepoxide with cashew nut oil in such amounts as to ensure equivalence between the phenolic hydroxyl groups of the cashew nut oil and the epoxy groups of the polyepoxide, and modifying the resulting reaction product with fatty acids having at least 8 carbon atoms per molecule, using a molar ratio of from 0.1:1 to 0.8:1 between said fatty acids and the cashew nut oil used in the reaction with the polyepoxide.
